What do you like best?
Wufoo is VERY easy to use, both to set up forms and for users to complete them. Any email addresses submitted via forms become auto-linked for administrators to see and immediately email on the back end. This makes communication on an individual basis very easy.
What do you dislike?
Once a form has been completed, it is a bit of a process for admins to search through completed records to find all the information you may be looking for. When exporting data, it becomes difficult to navigate everything that comes over, as Wufoo assigns its own information in columns along with all of the information you might need to sort through. An open-ended platform that has no direct integration with a current CRM makes entries in Wufoo difficult as well. If users who submit a form are unsure of anything (like a specific ID number), then it becomes difficult to match each form to a correct user within our company's CRM. Every question on each form is visible to administrators, even questions that do not appear when the user is completing the form. This further inundates the administrators when looking through submissions, as each form has questions left unanswered (since the user was never presented with the question).
